12 WARNING: Do not use the proportioner where water pressure exceeds 90 psig (620 KPa). Do not use the proportioner with a water supply temperature above 170°F (77°C). Use caution when handling chemicals; wear protective eyewear and gloves to prevent contact with the chemicals. Failure to follow these instructions may result in personal injury.

OPERATING INSTRUCTIONS/INSTALLATION DESCRIPTION The CIMCOOL Mix Master II is a simple, economical, and accurate method to mix CIMCOOL metalworking fluid concentrate with water. The most important requirement in the use of metalworking fluids is maintaining the proper mix ratio. The Mix Master II siphons concentrate from a 55 gallon or ( 200 L) drum and mixes it with water to supply approximately 3 to 4* gallons per minute of premixed fluid for an individual machine tool reservoir, central system, or premix tank. This is accomplished by a siphoning venturi operating on water pressure.

The two main requirements for

GUIDE

successful operation of the equipment are a minimum water pressure of 15 psig (101 KPa) (flow pressure) and selection of the proper metering tip.

The unit features a vacuum breaker to prevent backflow of fluid concentrate to the tap water line (in compliance with OSHA regulation 29 CFR section 1910.141 (b)(2)(iii)).

The unit also features a foot valve/ strainer to prevent backflow of concentrate into the drum.

* 3.7 gpm at 40 psig flow pressure (14 LPM at 275 KPa)

MAINTENANCE

Refer to your CIMCOOL Product Information Folder for selecting the proper metering tip to obtain the recommended metalworking fluid concentration. The mix ratios were obtained at a flow pressure of 40 psig (275 KPa). Checking the actual mix ratio or concentration obtained at startup with a refractometer or titration kit is recommended.

2. Using the fluid concentrate at room temperature.

Please be aware that changing the discharge hose length will affect the mix ratio. The discharge hose must have an open or gravity discharge and the flooding ring must be installed in the discharge hose for proper operation of the proportioner.

PROBLEM

(1) Install pressure regulator to minimize changes in tap pressure. Minimum flow pressure to be 15 psig (101 KPa).

1. Unable to obtain proper mix ratio

1. Installing a pressure regulator on the water line (remembering that the minimum water pressure is 15 psig (101 KPa) to operate the proportioner).

Clean with warm cleaning fluid (consider use of deionized water)

The CIMCOOL Mix Master II is a venturi type proportioner which depends on water prsesure and a metering tip to obtain a particular mix ratio.

One set (15 tips) of color-coded plastic metering tips is enclosed with each unit. Please refer to Table 1 for Tip Identification Chart.

Variation in fluid temperatures and water pressures will have a slight affect on the mix ratio. These variations can be minimized by

3. When mounting on a drum, tighten the bung swivel connector (turn clockwise to the drum).

TROUBLESHOOTING

Check venturi/metering tip for residue or scale

2. Insert the foot valve/siphon hose into the bung opening.

5. Select and insert the proper metering tip to use with the proportioner.

Thread the metering tip into the orifice retainer by hand. Do not over-tighten.

Check fluid temperature

1. Remove either the two inch (5.0 cm) or ¾ inch (1.9 cm) bung from the upright drum.

Check discharge hose/flooding ring

Two ¼ inch (.6 cm) holes are provided on the proportioner retaining bracket for wall mounting. The 2 inch (5.0 cm)

4. Install a water line (½ inch (1.3 cm) I.D.) to the proportioner. The proportioner has a ¾ inch (1.9 cm) female garden hose fitting water supply connection.

Check foot valve/strainer

The CIMCOOL Mix Master II has a bung swivel connector that makes it unnecessary to remove the tap water supply hose when changing from an empty to a full drum.

bung connector must be removed to mount the proportioner to the wall.

CORRECTIVE ACTION

The CIMCOOL Mix Master II is designed to be installed in the bung opening (either two inch (5.0 cm) or ¾ inch (1.9 cm)) of a 55 gallon (200 L) fluid concentrate drum. Alternately, the proportioner can be mounted on a wall.

The CIMCOOL Mix Master II Proportioner features simple operation and low maintenance. With few moving parts there is little to wear out. However, it is recommended that the venturi assembly and metering tip area are inspected periodically to insure that no
